9 to 5 Mac reports on a found screenshot of Apple's in-car system for iOS. The info came from a developer who apparently managed to unlock the hidden feature. The car interface was highlighted as a new feature of iOS 7 and is currently promoted on Apple's product page. It's yet to ship, but that may change with the pending iOS 7.1 release.

Besides the news that a developer was able to activate iOS in the Car before launch, the design shown in the images (above and below) show a user-interface that is strikingly different to the one shown at Apple's Worldwide Developers Conference in 2013 and on Apple's website.

iOS in the Car essentially allows your iOS device to interface with a compatible on-board computer. You can access iOS functions from from the car's in-dash display and controls.
